Answer:
6,000
Step-by-step explanation:
106,534 = 100,000 + 6,000 + 500 + 30 + 4
12 is 75% of what
is means equals, of means multiply
12 = 75% * what
12 = .75 * what
divide each side by .75
12/.75 = .75 * what /.75
16 = what
12 is 75 percent of 16
the answer is 16
The height of an equilateral triangle with side s is s*sqrt(3)/2
The area of an equilateral triangle is therefore s^2*sqrt(3)/4
The area of a hexagon with side s is 6 times the area of an equilateral triangle
=6*s^2*sqrt(3)/4
=3s^2*sqrt(3)/2
Here s=4,
Area of base (hexagon) = 3*4^2*sqrt(3)/2=24sqrt(3)
Volume of prism
=(base area)*height
=24sqrt(3)*9
=216sqrt(3)
Step-by-step explanation:
confidence coefficient for 99% is 2.58
2.58 * 19.4/sqrt(n) = 0.04
2.598*19.4/0.04 = sqrt(n)
( 2.598*19.4/0.04)^2 = n
1587676
